This appears to be the same issue that was resolved here:
Do you have white spaces in your file paths?
If so, I recommend using either the latest Food4Rhino installer or run the LB Versioner. Technically, this last issue didn’t get fixed until after the first post of the Food4Rhino installer (I updated it last week with the fix). S that might explain why the latest PollinationRHGHInstaller-latest.exe does not have the fix yet.
